The Service Discoverability principle is supported by the Standardized Service Contract principle in which of the following ways? Select the correct answer.
A. The Standardized Service Contract principle advocates using naming conventions for ensuring that the functionality of services is consistently expressed. By making the service easier to understand, it becomes more discoverable.
B. The Standardized Service Contract principle supports a design process whereby the service contract is customized and created prior to the service logic. This allows service designers to shape the service contract content in such a manner that it can be effectively discovered.C. The Standardized Service Contract principle requires the use of service contract design standards that can be created to establish conventions that are supportive of the Service Discoverability principle.

Often it is a requirement to wrap a legacy system with a service. This is typically accomplished by encapsulating calls to the legacy system’s Application Programming Interface (API) within the core logic of the service. Care must be taken to not expose details of the underlying API through the service contract as it may unintentionally couple the service consumer to the
legacy system. Which pair of service-orientation principles directly addresses this concern? Select the correct answer.
A. Service Loose Coupling, Service Abstraction
B. Service Statelessness, Service AutonomyC. Service Loose Coupling, Service Statelessness
D. Service Autonomy, Standardized Service ContractAnswer: AQUESTION: 40
